He said it was my car then because map 0 doesn't do anything. Took it off, haven't had an issue since. Just about everyone Ive heard of with a JB4 on this platform has been down the same path. They're garbage.

i thought you were running super fast? What happened? Ugh I'm beyond frustrated. I can deal with something not working, but making me slower is becoming an issue.

He answered me fast, still waiting on some responses but it was late last night. Ran like a monster but now I'm stuck in this limp mode and feel stupid. |
You're in the best hands possible if Terry is helping you. Have you tried a firmware upgrade (if one was available relative to current firmware)?
I assume you've tried this: sometimes, clearing isn't enough and the car needs to be driven for a few miles causing the code to clear itself. |
I'm on Version 9 with Version 10 Beta and 11 avail. I'm going to take the entire JB4 off, then wait for Terry to get back to me. Yes I've tried driving around after clearing and it still persists. I know you had good success your car is fast.
